What to do if the Viking Irrigation System fails to pump?
- B
  Benjamin VasquezJul 26, 2025
  If your Viking Irrigation System pump isn't pumping, ensure the supply container is full. Also, check and correct the valve position according to the instructions. Verify and correct the pump rotation. If there's insufficient head pressure, raise the supply container. Check the voltage if the pump isn't up to speed. Inspect and clean the Y-Strainer if the suction line is clogged, and check for air in the pump suction line.

Why Viking Irrigation System pump won't operate in automatic mode when the liquid level drops?
- D
  Dylan TurnerAug 2, 2025
  If the pump in your Viking Irrigation System isn't operating in Automatic mode when the liquid level in the tank drops, first verify that there is power at the unit terminal block. Ensure the liquid level in the tank is at the proper height by filling the tank. Check if the magnetic starter overload has tripped; if so, identify and fix the cause of the overload, then press the reset button on the starter. Also, check if the time delay is active and wait 10 minutes for it to time out. If none of these steps work, the pump motor may be defective and require replacement.

  Brian FlowersAug 7, 2025
  If your Viking Irrigation System unit will not turn on, check the power at both the supply and the unit and correct any issues. Also, check the fuses and replace them if required. Determine what caused the fuse to blow.

Why does my Viking Irrigation System have excessive power consumption?
- K
  Kevin VangAug 13, 2025
  If the pump in your Viking Irrigation System is consuming excessive power, it may be due to the pump not being fully broken in. Pumps usually draw higher current during the break-in period, and this should resolve itself after several weeks. If the issue persists beyond this period, manually turn the pump to check for mechanical damage. If you feel tight spots after the break-in period, contact Technical Services.

What to do if Viking Irrigation System pump doesn't operate in automatic mode due to high system pressure?
- A

  Verify that the system pressure switch setting is correct. Note that the CS-1 pressure switch setting must not be adjusted higher. Adjust the CS-1 switch setting lower if approved by the factory.
